这是我第一次尝试使用rails调试器.
还有任何建议的链接,以获得帮助开始使用rails调试器任何新手指南？
解决方法
确保在Gemfile中包含gem
gem 'ruby-debug' # for ruby 1.8.7+ gem 'ruby-debug19' # for ruby 1.9.2+
然后运行bundle install
更新：
您也可以将它添加到您的Gemfile中,它将处理两个ruby版本.
gem 'ruby-debug19',:require => 'ruby-debug',:platforms => :mri_19 gem 'ruby-debug',:platforms => :mri_18
